can there be a first moment?  whatever would have happened at that moment could have happened at a moment before that. but whatever would have happened at that moment, would have happened at the moment before that.

for anything to be, there had to be an ongoing event. an ongoing event which always was.  but which was undefined.

fluctuations of space  are an ongoing event.  fluctuations are transitory.  these fluctuations cancel out. when these fluctuations interphase with each other they are no longer transitory. phased fluctuations are persistent.

out of  the interaction of that ongoing event with itself,  an event is defined. defined events,  which change relative to other defined events, define time.

in the interaction of that ongoing event with itself, the occurrence of an event is defined.

fluctuations intertwine. equal and opposite changes in dimension intertwine.

change in space becomes constricted by previous changes in the dimensions of space.

phased fluctuations are changes in dimension; positive relative to negative. positive and negative dimension is a change in space.

phased fluctuations coalesce.

before the big bang.

beginning can only be defined relative  to not beginning: before. And being: after. but we can’t define before. without after.

but could, in the occurrence of that ongoing event, become defined in and of itself.
